I have no problem voicing my opinion whether it is liked or not. I own a SSA product. Unless I see some product design testing (by SSA) and specs it will be the last. MY OPINION -1 if you like. I guess you missed some of the info in the past. Anyway, the "Zcon" model line has been in the works on and off for a few years, but only recently did it get a name. There have been more then a few different big power prototypes that we tested and did not move forward with. We even flirted with a 4" coil, but did not go that direction. A couple of years ago, we had started to go with a massive triple stack driver. The output on that model was just bonkers, way more then any of our other models, but it did not have the clarity we require from our production sub woofers. Had a number of samples built up, there are a few videos on our channel with these installed, I believe the most viewed one is of John's green blazer. Over time, things got moved around, and other models were released first. A couple more prototypes went through Mark's truck, most recently the one with the two massive aero-ports. We do plenty of testing, Mark usually films his, I don't. The testing Mark does is more video friendly then my critical listening testing. As the Zcon model design is finally set, that is why we had a handful go out initially before they were actually for sale to the public. Knowing we could not send them out on the market just yet due to steel supplies, it was good to get a few out there in Team members vehicles and let them do some extended abuse testing in a number of different installs and power.
